Tufa tower.
They explain that the tufa columns formed underwater, when the water level was higher.
The lake has no natural outlet. Like the Great Salt Lake, it has high concentrations of minerals.
Below the lake there are and were freshwater springs. Each glob of tufa is the site of a spring.
Carbonate in the springwater combines with calcium in the lake water to form a kind of limestone.
